IMPROVEMENT IN TYPE-WRITING MACHINES.

Specification forming part of Letters Patent No. 1 81,463, dated August22, 1876 application filed February 5, 1876.;

To all whom it may concern:

Be it known that I, GEORGE H. MORGAN, of Alexandria, in the county ofAlexandria Machinery; and I do hereby declare that the following is afull, clear, and exact description: thereof, which will enable othersskilled in the art to-which it appertains to make arid use the same,reference being had to the accom panying drawings, and to'the letters ofreferoccupyz'. 0., properly spaced, or withproper spaces between theletters of each word, and

- between the words-themselves, and with mechanism so arranged that thespaces between the letters of each word,'and between the ing-hammer atthe right moment.

In this machine I accomplish the same result by means of a type-wheel,also; but the types are not arranged upon independent andadjustabletype-carriers, but are inserted radially in a revolving wheel,the letters of the different'alphabets or styles being inserted inparallel circles, each. style .in its own circlethatis to say, allthecapitals of the same style in one circle; all the common text-lettersof the same style in another circle, italics in another, and soon, eachdifferent style-or, size of letter having a circle of-its own, and sothat each'letter in its different-styles shall run in a line parallelwith theaxis of the wheel. Said improved wheel is made: adjustable,soas'to. bring thedesiredstyle of type opposite a fixed point Where therequired type is made, through suitable means, to receive an impulse ormotion which brings it in contact with the paper I to be printed. Theinvention furtherconsists in a new and improved mechanism for operatingthis new. type-wheel, said mechanism being hereinafter more fully setforth.

In the accompanyingdrawings, Figure l is a vertical sectional view ofamachine embodying my improvement. Fig. 2 is a side view of the same,also in vertical section. Fig. -3 isa plan view of the cylinder insection. Fig. 4 is a plan view of the type-wheel and cylinder, also insection. Fig. 5 is a vertical sectional view of the type-wheel,detached. Figs..6 and 7 show the detached view of the slidingc'am-rods.Figs-8 and 9 are detached views of the type-moving levers. Fig. 10 is a.detached view of the type, the stem ofthe type, and the spring forreturning the 'type to its normal position. Fig. 11 is a detached viewofoneof the cam-rods.

Referring to the parts by letters, A-represents the framework-towhich'the partsof the machine are journaled, or otherwise suitaablyattached. B represents a vertical shaft journaled in suitable bearingsin the frame A, =and0 is a horizonal shaft suitable to a journ'alin theframe A, by means of which mo- .tion is imparted to the machine,any'suitab'le power-being applied. D and D are beveled gear-wheels keyedupon the shafts OandB, respectively, through which the motionistrfansmitted.- F is a cylinder keyed to the shaft-B, so as to revolve withit. ,The upper portion of the cylinder Fis made of greater diameter than:thelower, and thewhole is formed with a series of longitudinal grooves,f, which extend throughout its length. A series of circumferentialgrooves, f ,are also formed inthe'periphery of the lower portion of thecylinder Theitwo upper of these circumfervential grooves f are formed onthe portion of the cylinder having the greatest diameter. E represents aseries'of rods 3 having cams-e on their upper ends, ,andga series ofgrooves, .3 corresponding in numberwith the circumferential grooves inthecylinder. 1 The end groove e hasa beveled face or cam, e Grepresentsaseriesof pivoted bars, the outer ends of the cylinder.

which are formed into finger-keys g. H represents a series of rods orvertical bars corresponding in number with the keys g. The lower endsare screw-threaded,and passed through slots in the bars G, andprovidedwith adjusting-screw wheels or nuts 9. h h represent spiralsprings, which encircle the lower ends of the bars H. The upper ends ofthese bars have each a cam orprojection, h. Irepresents a series ofhorizontal rods or bars, having projecting ends, provided with keys orcams 1'. These rods are pivoted to adjustable brackets J, secured to theframe of the machine, and are provided with springs j. p The keys Gr,rods H, and cam-bars I correspond in number with the circumferentialgrooves in the lower part' of the cylinder, and operate the rods E, inthe manner hereinafter more fully set forth. K represents a series of levers pivoted at the lower ends in the longitudinal grooves formed in theupper part of They also correspond in number with the rods E, cam-barsGr, rods H, and

keys g. On the'inner side of the upper end these levers K have acam-projection, k, and

on their other side a projection or key, k. L i it represents thetype-wheel loosely mounted on the shaft B, and made so as to fit over aportion of the upper end of the cylinder F, as shown in the drawings.

It is formed with a number of series of radial slots, 1, arrangedinparallel lines, as clearly shown in Fig. 5 of the drawings.

M represents the type, and N, type-shaft,

having a head or projection, 02, on its inner end. n represents spiralsprings placed around the stem N, which bear against the innerside ofthe outer plate of the type-wheehand against the head it. These type,with their stems and springs, are inserted in theslots l in the wheel.The wheel L has a central pro jection, L, on its upper side, formed witha circumferential groove, 1.

O is a sleeve, which may be made in two pieces and clamped together, andloosely mounted upon the shaft B. It has an annular key-ring. which fitsthe groove 1. One side of this sleeve 0 is formed into a rack-bar, 0.P'represents a segmental gear pivoted to the frame of the machine, andhaving teethwhich engage with the rack-bar 0. Q is alever, one

-end of which is secured to the pivotal shaft of the gear P, and itsother end passes out through the side of the machine, upon which isformed a series of notches, q, or other. means for securing the end of.the lever in the desired It is a band-wheel on the shaft 0.

I have not shown any device for carrying or feeding the paper in thisspecification but i the grooves f? on the enlarged upper portion of thecylinder Fare designed. for the recep-.

tion of the ends of cam-levers, which actuate mechanism for operatingthe paper-carriage, the paper being fed as indicated by dotted lines inFig. 2 of the drawings, S being afixed plate or platen, against whichthe paper is pressed by the type in the operation of printing.

The paper-carriage and mechanism for oper-.

ating the same will form the subject of another application for LettersPatent, for which I am about to apply. t

The operation of the machine is as follows: Motion being imparted to theshaft 0 by any suitable power, and the miter'wheels D l) gearing witheach other, the cylinder and type- Wheel will be rotated at the samerate of speed, the sleeve 0 remaining stationary, and

the ends of the cambars I being held clear of contact with the rods E bymeans of the springs j. When it is desired to print with the machine thetype-wheel L is adjusted up or down on the shaftB by means of theleverQ, segmentP, and rack o of the sleeve 0, so as to bring the head oftherequired type or style of type in its circle, to be printed, direct-,ly oppositetothe projections k on the upper end of the levers K. Thedesired style or size of type will now be in a position for printing.The operator then presses upon the key representingithe letter to beprinted, depressing the key end of the bar G, and raising theend towhichthe rod H is attached, thereby forc-.

ingthe latter upward, so that the -projection h on its upper endwillpress upon thecorresponding cam-bar Iuntil its key or cam 5 comes incontact with the beveled face of the rod E, pulling the latter down, sothat the projection or cam e on the upper end of the rod E will operateupon the projection k on lever K, and

force the projection 10 against the head of the type, so as to move thetype outward against the paper. i

The intermediatelever K may be dispensed with, and the rod E, throughits cam e, made to act directly on the inner end of the type, the stemof the type being suitably constructed for the purpose, and made toproject through an annular stay-plate on the inside of the type-wheel;but I prefer to use the. inter- I mediate lever K inconnection withrodE.

After the letter has been printed the stationary cam or plate :vwillcome in contact with the beveled face e as the cylinder revolves, andpush the rod E up again, so that the cam 0 will pass above the cam 70and permit the type to come back to its normal position through theoperation of the ispiral.

spring n. v t i t In doing this it will have forced the type out again,but at a time when it will not come in contact with the paper; As thetype-wheel revolves the type come in, contact with-the inking-rollerbefore coming tothe printingpoint, and the paper moves at the requiredrate of speed from right to left, it being operated by suitablemechanism, receiving motion from cam-levers, the ends of which. project.

into grooves f, as before described, so that the rods E will actuate thesaid leversat the same time that they operate the leversfor forcing outthe type. In this way the same mechanism moves the paper and prints theletter at one and the same time.

The second outward movement of the type, caused by the return or upwardmovement of the rod E, may be utilized to press the type against theinking-roller.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
